Hi Ben, just saw this, Very sorry to hear mate. Here is some pics up of the Turbo prior to fitting.
It's a proper garret spec GT3076r kit from GCG with the .82a/r housing and 4inch surge slotted inlet.
It was bought from a member in June 2011 who had a very minor front ender before it had even done 5000kms, which the insurance company wrote off.
I dont think it's serious mate. Current pics may help these guys diagnose. If you cant sort it Cooma Diesel in Fyshwick are the local Garrett rep.
